Active EA
Jamming: limit the effectiveness of enemy communications and detection systems
Deception: convey misleading information or deny valid information the enemy
Active Cancellation: theoretical system – involves sampling radar signal, analyzing, and returning out of phase.
EMP: electromagnetic radiation from a nuclear explosion or an electromagnetic bomb producing intense magnetic fluctuations.
Passive EA
Chaff: thin bits of aluminum or plastic
Infrared Countermeasures: flares
Towed Decoys: act as preferential targets
Radar Reflectors: concentrate the energy sent back the radar
Stealth: make less visible to radar/detection
Vehicle shape
Non-metallic airframe
Radar absorbing paint

Raytheon AN/APX – 100(V), IFF
Radar Warning Receivers (RWR)
Raytheon AN/ALR – 69(V)
Identification, Friend, or Foe (IFF)
Facilitates rapid engagement of enemy aircraft, conserves air defense assets, and reduces risk to friendly aircraft.
Pilot enters code in which others can identify as friendly, enemy, neutral.
AN/APX -100(V)
Data Link 16
Military inter-computer that allows aircraft, ships, and army units to exchange their tactical picture in real time.
Secure, high speed.
New Terminal =MIDS FDL
Radar Warning Receiver (RWR)
System shall detect, identify process and display AI, SAM, AAA weapon systems.
Should provide situation awareness, threat identification and integrated diagnostics.
Should provide the crew with the emitter mode and threat angle-of-arrival (AOA) information
AN/ALR – 69A(V)
